Abstract
The invention discloses a UPVC (ultra-rigid polyvinyl chloride) composite downcast pipe. The UPVC composite downcast pipe comprises a pipe body and pipe plugs, wherein the pipe body comprises an inner pipe and an outer pipe; at least three filter holes are formed in one end, which is close to the pipe plug, of the inner pipe; filter seams are uniformly distributed in a side surface of the outer pipe; the pipe plugs are conical pipe plugs; the inner pipe is a cast iron pipe; the outer pipe is a UPVC pipe; and the pipe plugs are cast iron pipe plugs. By using the design, compared with the downcast pipe with the original pipe plugs, the UPVC composite downcast pipe is easily inserted in the ground, and is easily pulled out after operation is finished, so that the downcast pipe can be repeatedly used. The filter seams are directly formed in the wall of the UPVC pipe by using a high slotting technology, sufficient water can be pumped out, small sand grains are directly filtered out of the wall of the pipe, only water is pumped, severe precipitation operation is guaranteed, and loss on a water pump and parts is reduced. Moreover, the UPVC composite downcast is made of UPVC materials completely, and is light in weight and convenient to mount; the labor intensity is greatly reduced; and the engineering efficiency is improved.
Description
Technical field
The present invention relates to a kind of downcomer, particularly a kind of UPVC composite water-reducing pipe.
Background technology
Market generally use be all cast iron pipe, specification is 4 meters or 6 meters one, on tube wall, process the chimney filter of 1 meter, the circular hole of manually beating 1-2 centimetre left and right diameter for chimney filter part, then the screen cloth of outsourcing different densities is built precipitation, but the easy oxide etch of cast iron pipe, the nylon wire wrapping also easily comes off or draws and splits in Precipitation Process, very easily cause silt to invade in tube wall, extract out in the lump or directly block in hole together with water layer, not only greatly reduce pump-out, and needs are often changed the component of suction pump, more seriously cause dewatering of foundation unbalanced, cause the more serious geological disasters such as surface settlement.Meanwhile, because the Heavy Weight of cast iron pipe own is all increasing very large cost of labor and labour intensity aspect installation and work progress and transportation.
Summary of the invention
Goal of the invention: the object of the invention is to solve existing rainfall pipe fragile, pump-out is low, the problem that weight is large.
Technical scheme: the invention provides following technical scheme: a kind of UPVC composite water-reducing pipe, comprises body and pipe plug; Described body comprises inner and outer tubes; Inner tube is provided with at least three filter openings near pipe plug one end; Outer tube side is evenly distributed with filter seam.
As optimization, described pipe plug is taper pipe plug.
As optimization, described inner tube is cast iron pipe, and described outer tube is UPVC pipe, and described pipe plug is cast iron pipe plug.
As optimization, described filter seam width is 0.25mm.
Operating principle: identical with existing downcomer using method.
Beneficial effect: the present invention compared with prior art: adopt design of the present invention, with respect to original pipe plug, be more easily inserted into undergroundly, after operation, be easy to again be extracted, to be repeatedly used.Outer tube is will filter seam by high-tech slot technology directly to process on UPVC tube wall, not only guarantee to extract out the sufficient water yield, and the tiny grains of sand are directly filtered outside tube wall, layer only draws water, guarantee strict precipitation operation, and reduced the loss to water pump and component.Meanwhile, near pipe plug one end, filter opening is set in inner tube and can utilizes hydraulic pressure that water is concentrated, accelerate to draw water efficiency.This UPVC composite water-reducing pipe is UPVC material, lightweight, easy for installation, greatly reduces labour intensity, has improved engineering efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of inner tube of the present invention.
The specific embodiment
A UPVC composite water-reducing pipe as shown in Figure 1, comprises body and pipe plug 1; Described body comprises inner tube 2 and outer tube 3; Inner tube 2 is provided with three filter openings 4 near pipe plug 1 one end; Outer tube 3 sides are evenly distributed with the filter seam 5 of 0.25mm.Described pipe plug 1 is taper pipe plug.Described inner tube is cast iron pipe, and described outer tube is UPVC pipe, and described pipe plug is cast iron pipe plug.
Claims (4)
